GWBASIC

Basic language command interpreter.

GWBASIC [file_name] [/c:n] [/d] [[/f:n] [/i]] [/m:[n][,nn]] [/s:n]

filename (v3.1)

Name of a GW-BASIC program file. The default extension is .BAS.

/c:n (v3.1)

Controls RS-232 communications. Allocates n bytes for the receive buffer and 128 bytes for the transmit buffer for each RS-232 card present. /c:0 disables RS-232 support. Defaults to 256 bytes.

/d (v3.1)

Allows ATN, COS, EXP, LOG, SIN, SQR, and TAN functions to return double-precision results. Approximately 3000 bytes of additional code space is used.

/f:n (v3.1)

Allocates maximum number of files opened simultaneously. Each file requires 194 bytes for the File Control Block (FCB) plus 128 bytes for the data buffer. The data buffer size may be altered using /s. Default is 3.

/i (v3.1)

Statically allocate file operation space for /s and /f.

/m:[n][,nn] (v3.1)

Sets n as the highest memory location and nn maximum block size (in multiples of 16) used by GW-BASIC. Defaults to 64K for data and stack segments. Used to reserve memory space for machine language subroutines beyond GW-BASIC's workspace.

/s:n (v3.1)

Sets maximum file record length. Default is 128, maximum is 32767.
